Special Equipment / Accessories:
Machining Process: Profile Grinding of Spur Gears by a profiled Grinding
Wheel, one or One or two flank grinding process, the workpiece is moving up
and down (Y-axis) and is Indexed from tooth to tooth by th B-Axis.
The grinding head has fixed angle for straight toothed gears.
BWO CNC Control Model 900 (German Manufacturer) for 4+2 Axis with dialogue
Programming of grinding programms based on the input data for an optimal
grinding process in combination with profile and lead modifications.
CNC-Controlled Grinding Wheel Dressing Device with motorized Diamantroll
mounted behind the Grinding wheel on a separate slide (Z-Axis) in
conjunction with the axis of the grinding slide ( X-Axis)
the software provides all modifications to involute basis profiles and
dressing cycles. Dressing time for redressing 15 seconds, new profile
generating takes 5 minutes dressing time.
